1 Claim.

My invention relates to improvements in inking attachments for hand stamps.

One object of my invention is to provide an attachment of this character which can be readily applied and used on any form of hand stamp and so arranged and constructed that it can be opened up or closed by the engagement thereof with a desk or the like.

Another object of my invention is to provide an attachment of this character in which the pad is normally held against the stamp so that both the stamp and the pad are protected against dust and the atmosphere, and, therefore, a better impression can at all times be made.

A further object of my invention is to provide a simple cheap and effective inking attachment having certain details of structure and combination of parts hereinafter more fully described.

In the accompanying drawing:

Figure 1 is a side elevation of a date hand stamp, showing my improved inking attachment applied thereto;

Figure 2 is an end view of Fig. 1; Figure 3 is an end view, showing the act of releasing the inking pad and the pad in dotted lines in open position;

Figure 4 is an end view, showing the act of closing the inking pad;

Figure 5 is an enlarged top plan view of the inking attachment removed from the frame of the hand stamp;

Figure 6 is a vertical sectional view taken on the line 6-6 of Fig. 5;

Referring now to the drawing, I represents the frame of an ordinary dating stamp, and 2 the base to which the die plate is attached by a set screw, or any other means, which forms no part of my invention, but is shown to illustrate the application of my invention to this form of stamp.

My improved inking attachment as applied to this form of stamp, comprises a die plate 3, having on its upper face, at one side, inwardly turned lugs 4, passing over the upper face of the base 2, the opposite side of which is provided with an upwardly extending ear 5, through which is screwed the thumb-screw 6, the inner end of which passes over the base 3, whereby the die plate is removably carried by the frame. In this form of stamp the die plate is provided with a central opening I, through which passes the date type 8, as shown in Figure 4 of the drawing.

Pivotally mounted at 9, to one end of the die plate 3, is a housing II), in which is arranged the ink pad II. The die plate 3 is provided with two cars l2 and I3, and the housing In is provided with two ears l4 and I5. Passing through said ears is the pivot 9, as clearly shown in Figure 5 of the drawing. Surrounding the pivot 9, between the ears on the die plate, is a coil spring 16, having one end engaging the lower face of the 5 die plate, and its opposite end engaging the inner face of the end wall of the housing In, whereby it is at all times exerting an opening pressure to cause the housing to assume the position shown in dotted lines in Figure 3 of the drawing. The 10 housing I0 is of a size approximately that of the die plate. The end opposite the hinge is provided with an opening 11, adapted to receive a pivoted catch carried by the die plate 3.

This catch comprises a fiat plate I8 pivoted at 15 Hi to the upper face of the die plate 3, and rigidly carries the downwardly extending pin 20, having the hooked end I2 extending through the opening 22 in the housing, as clearly shown in'Fig. 6 of the drawing. The plate I3 has at one edge an 20 outwardly curved portion 23, which, as shown in Fig. 5 of the drawing, extends out beyond the end of the die plate 3. A leaf spring 24 is secured around the pivot l9 and has a downwardly turned end 25 engaging the pin 20 and normally exerts 5 an outward pressure on the catch, whereby the same is held in the position shown in Fig. 5. The hooked end of the catch 2| is provided with a beveled portion 26, which is engaged by the edge of the housing when it is open so that the 30 catch is forced inwardly to allow the housing to assume the position shown in Figs. 3 and 6 of the drawing.

While I have shown the specific form of latch, it will be understood that the same may be 35 greatly varied without departing from the spirit of my invention.

While I have also shown my invention as applied to a date stamp, it will be understood that the same may be applied and used on any type 40 of stamp, such as stamps on which the rubber stamp is secured to a wooden block, or a pocket stamp in which the die plate would have a folding handle.

In the operation of the stamp, it will be under- 45 stood that the housing carrying the pad is normally closed, and in the position shown in Figures 1, 2, and 3 of the drawing. When it is desired to use the stamp, it is only necessary to take it in the hand and place it in the position 50 shown in Fig. 3 of the drawing. By a downward pressure, or a slight knock on the desk, the outwardly curved portion ll of the catch plate will engage the desk and force the same inwardly and the hooked end Hi to pass inwardly beyond the 55 wall of the opening l2, and the spring 28 will cause the housing Ii) to swing upwardly, as shown in dotted lines in Figure 3, and remain in said position. From this position it will be seen that the housing is in a line beyond or above the lower face of the die plate, so that the pad housing in no way interfere with the normal stamping operation. When you are through with the stamp it is turned in a reverse position to that shown in Figure 3 of the drawing, allowing the pad housing to engage the desk, and by a slight downward and horizontal movement of the stamp, the housing is swung on its pivot to a position at right angles to the die plate, and resting on the desk. By an upward movement of the stamp, the die plate is swung over so that the catch automatically locks the pad housing in its normal position.

From the foregoing description, it will be seen that applicant does not have to operate the catch by a separate operation of the hand in either opening or closing the pad housing over the end of the die plate.

Having thus described my invention, what I claim is:

A stamp comprising a frame and a die plate, an inking pad pivotally mounted upon the die plate at one edge, spring means for holding the pad out of engagement with the die plate, a pivoted member mounted upon the upper face of the die plate adjacent the opposite edge from the pivot of the inking pad, a spring pressed catch rigidly carried by the pivoted member and extending through an opening in the die plate and entering an opening in the side wall of the pad for holding the pad tightly against the die plate, said pivoted member having a portion extending beyond the edge of the die plate and adapted to release the catch upon engagement with an object, whereby the pad is moved around above or beyond the lower face of the die plate.
